The disclosure includes a connection method to connect a shaft to a body. The body and movable latch may be an integral single molded plastic part connected by a flexible hinge, bushing, or a multipart hinge. In operation actuating the movable latch to raise or lower a latching beak within a corresponding open guide in the plastic body. A shaft into a shaft guide in the body which intersects the beak guide to temporarily latching the shaft to the body via a mounting fixture the shaft with the beak; and, wherein the body has a face end and a tail end.

Claims (39)

1. An ergonomic quick release system comprising:

a plastic molded handle with a front half section and a back half section

the front section comprising:

a face end with an interface comprising:

a shaft guide collinear with the interface configured to accept a shaft; and

a fixing guide distal to said shaft guide and having a flat section connected to and raised above said shaft guide, wherein said fixing guide has a smaller inner diameter relative to said shaft guide;

a beak guide with an open top and an open bottom generally perpendicular to the shaft guide and intersecting the interface;

said shaft having a distal end having a flat section configured to mate with said flat section on said fixing guide and having a mounting fixture;

a plastic movable latch with a tab lock formed therein; and

a flexible integrally molded plastic region extending from an actuation surface of the front section forming a hinge;

wherein the hinge terminates in a body tab which is configured to be fixed in the tab lock,

wherein the plastic movable latch has a first side, a second side and a middle region;

wherein the first side faces the actuation surface and a beak extends therefrom; wherein the beak forms a latch cooperating with the mounting fixture; and

wherein pressing on the movable latch lifts the beak out of the mounting fixture.

2. The system of claim 1 further comprising:

an active region on one side of the middle region and an inactive region on the other side of the middle region; and,

wherein the beak extends from the inactive region.

3. The system of claim 2 wherein depressing the active region compresses a portion of a bushing and raises the inactive region and beak thereby unlatching the shaft.

4. The system of claim 2 further comprising raised ribs on one of the active and inactive region.

5. The system of claim 1 wherein the movable latch is fixed via said body tab and said tab lock in a neutral position.

6. An ergonomic quick release system comprising:

a plastic molded handle with a front half section having an

actuation region and a back half section;

the front section comprising:

a face end with an interface comprising:

a shaft guide collinear with the interface configured to accept a shaft; and

a fixing guide distal to said shaft guide and having a flat section connected to and raised above said shaft guide, wherein said fixing guide has a smaller inner diameter relative to said shaft guide;

a beak guide with an open top and an open bottom generally perpendicular to the shaft guide and intersecting the interface;

said shaft having a distal end having a flat section configured to mate with said flat section on said shaft guide and having a mounting fixture and;

a plastic movable latch with flexible integrally molded plastic region extending therefrom forming a hinge having a bottom;

a latch tab at the said bottom of said hinge; and

a tab lock at the actuation region of the front section and configured to accept and fix the latch tab;

wherein the plastic movable latch has a first side, a second side and a middle region;

wherein the first side faces the actuation region and a beak extends therefrom; wherein the beak forms a latch cooperating with the mounting fixture; and

wherein pressing on the movable latch lifts the beak out of the mounting fixture.

7. The system of claim 6 further comprising:

an active region on one side of the middle region and an inactive region on the other side of the middle region; and,

wherein the beak extends from the inactive region.

8. The system of claim 7 further comprising physical cues on one of the active and inactive region.
